[ardour-users] Problems with Jack and Ardour/Rosegarden

Hi all!

I have been tweaking Jack 0.99 and Ardour up from source for my AMD
Athlon 64 bok running Fedora Core 2 x86_64 for a while. I'm getting a
huge amount of XRuns so I decided to try realtime-lsm-0.1.1. So I had to
compile my kernel to enable that module to load up.

Everything compiled fine after a bit of a struggle but the XRuns are
still there. Also if I tweak the Jack settings with qjackctl so that my
latency is 5,9ms I get 89% of CPU usage just running Jack.

If the realtime module is loaded then the Ardour can't connect to Jack.
Jack reports unability to create a thread.

If you have time I would really appreciate your help. There's a forum
thread going on at
http://www.linuxquestions.org/questions/showthread.php?s=&threadid=261015 where I have tried to explain and solve the problem. Thank You in advance.

Best Regards:
